US President Donald Trump has signed an executive order imposing 50% tariffs on a wide range of goods imported from Canada, in retaliation for what he described as "unequal treatment" of US cars, dairy, and alcohol.

The duties take effect on August 19 and mark a major escalation in trade tensions between the North American neighbors. The White House stated that the tariffs are necessary to protect American businesses.

Targeted goods range from everyday consumer items such as wine and hockey sticks to industrial goods like commercial cement. However, several key exports will be spared, including energy, potash, critical minerals, and fish.

The new duties build on existing trade barriers between the two nations. The US has been maintaining active tariffs ranging from 15% to 50% on Canadian steel, aluminum, and copper. Washington also charges a 35% tariff on Canadian softwood lumber, alongside a 25% tax on non-US parts in cars.

Canada has its own 25% counter-tariff on selected imports of American steel, aluminum, and vehicles. Monday's duties come in the wake of President Trump's threat to impose tariffs over Canadian wildfire smoke drifting into US cities.
